How to Create an APA Style Appendix | Format & Examples

An appendix is a section at the end of an academic text where you include extra information that doesn’t fit into the main text. The plural of appendix is “appendices.”

In an APA Style paper, appendices are placed at the very end, after the reference list.

Do I need an appendix?

You don’t always need to include any appendices. An appendix should present information that supplements the reader’s understanding of your research but is not essential to the argument of your paper. Essential information is included in the main text.

For example, you might include some of the following in an appendix:

• Full transcripts of interviews you conducted (which you can quote from in the main text)
• Documents used in your research, such as questionnaires, instructions, tests, or scales
• Detailed statistical data (often presented in tables or figures)
• Detailed descriptions of equipment used

You should refer to each appendix at least once in the main text. If you don’t refer to any information from an appendix, it should not be included.

When you discuss information that can be found in an appendix, state this the first time you refer to it:

Note that, if you refer to the same interviews again, it’s not necessary to mention the appendix each time.

Appendix format example

The appendix label appears at the top of the page, bold and centered. On the next line, include a descriptive title, also bold and centered.

The text is presented in general APA format: left-aligned, double-spaced, and with page numbers in the top right corner. Start a new page for each new appendix.

The example image below shows how to format an APA Style appendix.

Organizing and labeling your appendices

If you include just one appendix, it is simply called “Appendix” and referred to as such in-text:

When more than one appendix is included, they are labeled “Appendix A,” “Appendix B,” and so on.

Present and label your appendices in the order they are referred to in the main text.

Labeling tables and figures in appendices

An appendix may include (or consist entirely of) tables and/or figures. Present these according to the same formatting rules as in the main text.

Tables and figures included in appendices are labeled differently, however. Use the appendix’s letter in addition to a number. Tables and figures are still numbered separately and according to the order they’re referred to in the appendix.

For example, in Appendix A, your tables are Table A1, Table A2, etc; your figures are Figure A1, Figure A2, etc.

The numbering restarts with each appendix: For example, the first table in Appendix B is Table B1; the first figure in Appendix C is Figure C1; and so on. If you only have one appendix, use A1, A2, etc.

If you want to refer specifically to a table or figure from an appendix in the main text, use the table or figure’s label (e.g. “see Table A3”).

If an appendix consists entirely of a single table or figure, simply use the appendix label to refer to the table or figure. For example, if Appendix C is just a table, refer to the table as “Appendix C,” and don’t add an additional label or title for the table itself.

Frequently asked questions

What is an appendix?

An appendix contains information that supplements the reader’s understanding of your research but is not essential to it. For example:

• Interview transcripts
• Questionnaires
• Raw data
• Detailed descriptions of equipment

Something is only worth including as an appendix if you refer to information from it at some point in the text (e.g. quoting from an interview transcript). If you don’t, it should probably be removed.

Where do appendices go in an APA Style paper?

Appendices in an APA Style paper appear right at the end, after the reference list and after your tables and figures if you’ve also included these at the end.

Do I need to number my appendices in APA Style?

When you include more than one appendix in an APA Style paper, they should be labeled “Appendix A,” “Appendix B,” and so on.

When you only include a single appendix, it is simply called “Appendix” and referred to as such in the main text.

(see Appendix)

Can I cite sources in an appendix?

Yes, if relevant you can and should include APA in-text citations in your appendices. Use author-date citations as you do in the main text.

Any sources cited in your appendices should appear in your reference list. Do not create a separate reference list for your appendices.
